Signs You Need to Be Getting More Vitamin D

Vitamin D is a fat-soluble vitamin in a family of compounds that includes vitamins D1, D2, and D3. It can affect as many as 2,000 genes in the body.  But signs that you're low on the nutrient are a bit quieter. If you notice one or more of these issues, head to your physician to get your blood tested. But don't reach for supplements quite yet—you'll want to make sure it's a vitamin D deficiency you're dealing with first since excessive intake of the nutrient can be linked to its own health concerns.)

Decreased muscular size can be the result of not enough vitamin D in muscle and nerve tissue, says Kimberly Mueller, R.D., owner of Fuel Factor Nutrition Coaching. So if you notice that you can't eek out the same number of reps you've always done, that may be a sign you need more vitamin D.


Depression among women

According to a study in The Journal of Clinical Endocrinology & Metabolism, women with low levels of D are twice as likely to combat depression.

Greater Pain Sensitivity

Chronic Pain

Insufficient levels of vitamin D have been linked to chronic pain.

Stress Fractures

Vitamin D promotes bone growth—but when you're low in the nutrient, your bones become weakened, meaning your risk for stress fractures increases, says Mueller. In fact, some studies show as high as double the risk if vitamin D levels are exceptionally low.

High Blood Pressure

Before you blame your grouchiness on PMS, know that D affects the levels of serotonin in your brain—which also impacts your mood.
